Bromocresol Purple Free Acid Introduction
It is a kind of "color-developing sentry" that changes color when it meets acid and alkali, and its core function is to "see" the acid and alkali degree of liquid. It works in the range from weak acid to weak base. When the liquid is acidic, it turns yellow, and when it is alkaline, it turns purple-blue. It changes color by changing its structure with the number of hydrogen ions. Drop it into solution, culture medium or detection reagent, and you can judge whether the environment is acidic or alkaline by looking at the color with the naked eye. It is often used to help the laboratory keep an eye on the reaction progress, distinguish the acid production of bacteria, or assist in measuring the amount of protein in the blood.

Application Areas:
1.Laboratory test: make acid-base indicator and judge acid-base by the color of solution.
2.Microbial culture: add it to the culture medium to see if the bacteria produce acid to distinguish the strains.
3.Clinical test: assisting in measuring blood protein content and helping doctors to see the indicators.
4.Sterilization monitoring: put it in the sterilization indicator to see if sterilization is qualified by color change.
Main Benefits:
1. Sensitive color change: the color changes when the acid and alkali are fine-tuned, and the color contrast is strong, which is easy to distinguish with the naked eye.
2. The dosage is extremely low: Bromocresol Purple Free Acid can develop color in a small amount, with low cost and does not interfere with the reaction of the original solution.
3. Stable and durable: not easy to decompose and deteriorate, can be stored for a long time, and is suitable for conventional storage.

FAQ
Q1:What is the pH of bromocresol purple?
A1:It is yellow at pH 5.2 and becomes purple at pH 6.8 .
Q2:What's the difference between Bromocresol Purple Free Acid and sodium salt version?
A2:Free acid is a direct acidic form, and its dissolution and color development behavior are different. Sodium salt has been neutralized, and it is selected according to the formula requirements.
Q3:How long is the shelf life? How to save it?
A3: It is usually 36-60 months to seal the place away from light and dry at room temperature; Caking due to moisture does not affect the purity but is difficult to weigh.
